Abstract
A directional horn may include at least one group of a plurality of speakers or audio emitters. The audio emitters may each emit and audio signal at a same frequency. A processor may control a relative phase difference and relative gain difference between each audio signal, based on a determined direction. The directional horn may be positioned on a vehicle. The determined direction may be based on a direction indicated by a driver controlling the vehicle, external environmental factors, vehicle dynamics, or other factors.
